Slide 214
 The bottom plate lift sensor determines whether the plate needs lifting.
 When an original is placed on the original tray: The original set sensor
switches on, the pick-up roller drops, and the sensor (on the pick-up
roller assembly) switches off. Then, the motor lifts the lever, raising the
bottom plate.
 When the bottom plate reaches the correct feed position: The sensor
switches off and the motor stops.
 During the job, when the top of the stack becomes too low: When the
pick-up roller drops low enough to switch the sensor on again, the
motor switches on again to raise the stack to the correct feed position.
 At the end of a job, the bottom plate is lowered until the bottom plate HP
sensor (not shown here) detects it.
